vTo all whom t may/concern:

Beit known that l, WILLIAM N. BEACH, a

.citizen of the United States, and aresident separators, and has specially in view a sepa# rating mechanism adaptedspecially for use in connection with cement-millsifor separating the iineround cement from the coarser cement ming ed therewith.

To this end the invention contemplates a simple and practical construction of separator possessing special utility as a separating means for granular substances and serving to insure an effectual separation of fine and coarse particles and causing the separate discharge thereof from the machine.

A special object of the invention is to iinprove that type of separators relying upon both centrifugal force and the action of a suction appliance to secure the proper separation of iine and coarse particles or particles of different specific gravities.

In this connection the invention contemplates improved feeding and distributing means for the material to be separated and a 'novel mounting thereof in relation to the inner and outer collecting-cones and the suction appliance. v i

, With these and many other objects in view, which will more readily appear as the nature of the inventionisbetter understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter'more fully described and claimed.

. The essential features of the invention involved in carr ing out the foregoing objects are necessari y susceptible to structural change without departing from the scope of the invention; but aprcferred embodiment of the invention is shown in the accompanyin drawings, in whichigure 1 is a vertical longitudinal sectional view of a separator` embodying the present improvements. Fig. 2 is a partial top plan view on the line 2 2 of Fig. 1, showing a portion of the suction-fan in combination with the rotary feeding-chute with which it is associated. Fig. 3 is an enlarged sectional View of the feeding and distributing devices [for the separator and the driving means therefor.

Like references designate corresponding parts in the several figures of the 'lrawings.

`In carrying out the present invention Athe special improvements claimed herein are preferably associated with .a separator-casing of the type shown in the drawings and designated in its entirety by the referencenumeral 1. The said casing lis constructed with the inner and outer collectingfcones 2 and 3, respectively, which are arranged in yspaced relation suitably braced apart to constitute separate collecting and receiving chambers for the different grades of material separated through the action of the niacliine. The outer collecting-cone .'Sconstitutes a conical bottoni continuation of the main upper cylindrical part of the casing, While the inner cone 2 is arranged in concentric spaced relation to the outer cono` 3 and has fitted Within the upper open base portion thereof an upwardly-tapering suction-funnel 4. This funnel 4 is open at top and bottom and is supported at its lower edge in spaced relation to the wall of the cone 2 through the medium Vof a plurality of supporting and bracing legs 5, secured to the bottom edge of the funnel 4 and to the inner side of the inner cone 2 near the upper edge of the latter. In addition to the suctionfunnel 4, su ported centrall within the up per part of the inner cone 2, t e latter has also iitted to its extreme upper edge an upstand ing annular air-feeding frame 6, projecting above the said inner cone to substantially the plane of the top opening of the suction funnel 4. The said annular air-feeding frame 6 is in theform of a ring or band constituting what might be termed a partition between thenpper ends of the inner and outer cones, and said frame is provided therein with a continuous series of air-cire culating ports 7, adapted tobe covered or uncovered to the desired extent through the medium of an annular controlling shutters'lide 8. This shutter-slide 8 acts in the capacity of a controlling-valve for varying the size of the openings 7 and is also provided with a continuous series of valve-openings 9, working over the' said openings 7, so that by the turning of the slide S to any set positionv the desired quantity of air for feedingfrom the vouter com` into the inner cone may be on the upper cud of the Shutter-slide 8 and extends downward so as to cover the air-cir back into the chamber 2.

Aside frein the structural features referred to the separator-casing 1 is provided at the apex or lower end of itscuter collecting-cone 3 with a bottom discharge opening or spout l() for the grade-,of n1 ate'fial collected by the outer cone 3, while the inner of thecollecting-cones 2 is provided at its apex or lower end with va bottom discharge-opening 11, connnunicating with a discharging-pipe 12, fitted to the apex of the cone 2 and projecting' through the wall of theyouter cone 3 into the upper end of an outlet-spout 13, fitted to one side of the outer cone 3.I continuous to: the lower extremity thereof. only receives the 'discharging material frein the inner cone 2, but is also provided with a side air-feeding port 14, substantially in line with the discharging-pipe 12 and affording an air-.inlet throughwhich air is taken into the apparatus.

The separator-casing l is provided in the top part thereof, above the plane of the suction-funnel -l and the air-feeding franie 6, with a top fan-chamber 15, within which is niounted a horizontal suction-fan 16. This suction-fan 16 is arranged for rotation above the plane of the funnel et and the fraine 6 and essentially consists of a plurality of rzuliallyarranged fan-blades 17, suitably braced upon and carried by a series of radial spokes 13, which in the present invention are preferably mounted directly upon the attaching lugs or elements 1S), carried upon the external periphery of a rotary tubular feeding-chute 20. This feeding-chute 20 is in the forni of'- a cylinder or tube, .havingan upper flaring or-conical portion 21 and open at both ends.- Below its upper flaring or conical portion 21 the said feeding-chute 2U has arranged therein a circular series of spaced radial and spirallydisposed distributing-blades 22. tributing-blades 22 are integral with or otherwise-rigidly itted to the rotary feeding-chute 20 and lie directly below the top opening of' said chute, so as to receive the granular material freni the inlet or supply spout 23, entering the separator-casing at the top and center thereof.

The Vrotary feeding-chute 20, equipped with the radial and spiral distributing-blades The outlet-spout 13 not- These dis- 22 referred to, is provided with a central longitudinal hub 24, fitted upon the inner end portion of a vertically-disposed rotary sleeveshaft 25. yThis sleeve-shaft projects through the 'top of the separator-casing and extends through the upper and lower bearings 26 and 27 of a gear-case 28, surincunting the separater-casing. Als'o the sleeve-shaft 25 hasl mounted thereon within the gear-case the .unter-gear 29, nieshing with a similar gear 30, likewise located within the case 28 and mounted upon the innerend 'of a drivingshaft 31, carrying the beltepulleys. 32. ter receiving the driving-belt inthe vusual manner.

One of the-' -distinctive features of the invention resides in associ-ating with the feeding-chute 20 a rotary di'eiectoretable ,33. This table is in the forni of a vdisk arranged l"belowthelower end ofthe chute 20 and provided at its edge with a peripheral upstandingV defleeting-lip 34, which is designei'll tov defleet the .material upwardly against av baflieplate 35, arranged above and in spaced relation to theA table 33 and of greater 'diameter than the saine. The said baffle-plate 35, which lies directly above the table 33is rigidly connected thereto and held in spaced relation therefrom through the inediuni of a plurality of connectors 36, and thp said baffle-plate 35 is also provided with an upstandgaging the exterior of the feeding-chute 20. The deilector-table 33, and hence the bafile-plate 35 supported thereby, arefearried upon. the lower end of a shaft-rod 3S, extending longitudinally through the sleeve-shafty 25 and provided with a threaded upper end 39, receiving thereonan adjusting-nut 40, adapted to engage against the binding cap or collar 41, which is held in clamping engage- 'inent with the upper end of the sleeve-shaft 25, thus providing a connection between such shaft and the shaft-rod, so that these parts will rotate in unison. At the same time the construction described perniits of the vertical adjustment of the shaft-rod with reference to the betto'nrof the feedingchute to suit the conditions under which the separation is carried out.

In the operation of the machine the cement or other material is fed through the inlet orsu'pply spout 23 and is directed into the upper receiving end of the feeding-chute 20. T rough the rotary :motion of thisl feedingchute the distributing-blades 22 thereof tend to distribute the fine cement over the deliector-table 33. The material which is thus deposited on said table is caused by the centrifugal force, due tothe-rotation thereof, to fly outward until it strikes the lip 34, "This lip serves to deflect the particles upward against the'bafle-plate 35, andvtheheavier and larger parts are again deflected from said baille-plate and ily in a downward direction, whereas the lighter particles are drawn by IIO , 95 ing guiding-sleeve extenslon 357, shidably enthe suction-tunnel 4 and pass the suction of thefftanfthrough the open top of through the ian and into the outer cone 3. The heavier articles, which are defiected downwardly trom the bathe-plate, pass intothe inner cone 2 and are carried away through the pipe 12 and the outlet-spout '13 back'to the grindingmachine, where they are reground. ,i

While the air-feeding!v ort 14 supplies air to the machine through-,4 e inner cone 2, the air-circulating orts 7 0i the frame 6 permit air tobe taken lrom the outer cone 3 into the inner cone 2. As-already pointed out, the size ofthe openings myberegulated through lthe adjustment of thfi"y rotaryshutter-slide -or valve 8.

` When very fine material is to be selected,

the detlector-table and the 'baiile-plate 35 are' adjusted farther away from the lower end y of the feeding-chute and the top opening of the funnel 4,. so that-'the suction to which the particles are subjected is reduced. When it is the said members 33 and 35 are elevated, so that-the particles are subjected to a stronger suction. v From the fore oing it-is thought that the construction, operation, and many advantages of the herein-described separator will be readilyfapparent without further description.

Having thus described my invention, what I claim is- Y 1. .In a separator, a separator-casing having separate collecting-chambers, a rotaryV feeding-chute arranged within the top-part of the casing, a suction-ian located above the lower end oi' the chute, a rotary distributingthe lower end of the table mounted below feeding-'chute and carried therewith, said table having a vertical adjustment. independent of the chute, and provided with a periphl eral upstanding deiiecting-lip, and a battleplate supported and carried by the distributving-'table and arranged above the same.
